BlackICE Historical Immersion Mod 1.16.10

Description


We aim to bring Hearts of Iron 4 to an all new level, making your game experience more immersive, historical and challenging.
Black ICE completely overhauls most national focus trees, changes game mechanics, adds in tons of events, technologies, units and much more.
While playing ahistorical will work, Black ICE mainly aims at improving the plausible historical experience.



Current BICE version: v9.2.0 - Checksum: 0f43
Supported HOI4 version: 1.16.10

Supported game language: English ONLY (other languages will produce errors!)

Make sure to ONLY use Black ICE, as any other loaded mod most likely will cause issues. Even purely cosmetic mods have been known to cause problems.



- New and improved national focus trees for all majors and most minor nations
- Hundreds of new techs to research, including country-specific armor, aircraft, and ships
- Completely revamped naval system. Customize your ship classes or rely on premade historical designs
- Air War with realistic losses and improved gameplay
- Dozens of new battalion and support unit types
- Extended laws and politics that allow you to fine-tune your strategy
- Immensely detailed, all-new production system, which provides a much more detailed approach to unit equipment
- Events and decisions to completely immerse you in the game and the history it follows
- Improved AI across the board to provide for a more unique challenge



We are proud of our amazing community! Your feedback, praise and constructive criticism drives the project forward, and we are very thankful for it!
Our main hub of activity is our Discord, which currently hosts approximately 6,000 members. Ask questions, be in direct contact with the Devs and coordinate your next BICE Multiplayer game.

Of course a project of such scope does not come without bugs, and we are truly thankful for any messages that bring them to our attention, either here or in the Discord.
Please keep in mind that this is a project we are doing in our free time, so keep it civil. Nobody is forcing you to play the mod. (Although we think you should definitely be playing it!).

Alas, a lot of issues and bugs are out of our hands, as they are a result of un-moddable assets from Paradox.

Go here for the official Paradox troubleshooting in case your game doesn't load, or if it crashes.[support.paradoxplaza.com]



Black ICE has and is being worked on by a lot of dedicated people, and many countless hours have gone into it.

@annabecella, some parts of the tree only become visible at a certain time (or after some events) and other parts vanish. It is slightly annoying because USSR is short of time to do all its desirable foci and you can't see how long the Baltic focuses will take to complete.
